More than 2.5 million UK motorists could be driving with an invalid car insurance policy, having provided inaccurate information during application, a new report has revealed.

Independent price comparison service uSwitch.com found that ten per cent of drivers lie to car insurance providers when applying for a policy.

Over 750,000 fail to mention previous driving convictions, while 1.5 million intentionally lie about personal details such as age and address, despite the fact that three out of four are aware that providing false information could invalidate their policy.

In addition, the website also found that six per cent of cars on UK roads were being operated without any insurance whatsoever.

Aron Thompson, head of insurance at uSwitch.com, said: "With many consumers seeing car insurance as a grudge purchase, it's no great surprise to see people either withhold or knowingly provide inaccurate, crucial information in order to get cheaper cover.

"To the consumer, this may seem like a little white lie to save money. In reality, it could end up teaching the driver a costly lesson, on average £1,636, as the provider is under no obligation to settle a claim based on a policy which is inaccurate."
